As I prepare for interviews I have become obsessed with these online forums because they are fun. Anyway, I don't know if there has been a guys input on the issue of what to wear yet. As my user name suggests this is my third year at trying to get in (will be last either way). I have been to many interviews before and I am always really interested in the people's dress. I've noticed that on the night before graduate student meet and greet that most applicants are dressed up like a nice dinner. Like one girl said dark jeans and a nice shirt would probably be acceptable. I love cardigans and my wife wears them all the time so I have a bias towards those I'm sure you could wear one at the meet and greet. I've noticed normally the grad students are dressed down more than the applicants. I don't think I've been to an interview when the women aren't wearing a skirt or pant suit. Most of the interviews do involve a lot of walking around the campus and to and from faculty rooms so definitely comfortable shoes are a must. All right that's my two cents. good luck everyone.
